WPF中的网格扩展

Question

Hai 目前我有这样的网格。

<Grid Name="tGrid1" Grid.Row="0" Background="Black" > 
    </Grid> 



    <Grid Name="Grid2" Grid.Row="1" Background="LightBlue" > 
    </Grid> 



    <Grid Name="Grid3" Grid.Row="2" Background="LightGray" Height="auto" > 

    </Grid> 




    <Grid Name="Grid4" Grid.Row="3" Background="LightGreen" > 
    <Button HorizontalAlignment="Left" IsEnabled="True" Margin="13.5,5,0,5" Name="TestBtn" Width="50" Click="test_Click" >Test</Button> 
    </Grid> 

</Grid> 

我想要的是，当我点击测试按钮电网1和电网2有倒塌的空间已被占用与网格3对应。这意味着外部网格的总高度为500，网格3应该占据高度= 465，并且网格4应该打开y身高= 35。 我该怎么做？我应该如何改变我的网格高度定义？ Thanx提前 卡娅

海 我找到了解决办法。

<DockPanel > 
<Grid Name="tGrid1" Grid.Row="0" DockPanel.dock="Top" Background="Black" > 
</Grid> 

<Grid Name="Grid2" Grid.Row="1" DockPanel.dock="Top" Background="LightBlue" > 
</Grid> 

<Grid Name="Grid4" Grid.Row="3" DockPanel.dock="Bottom" Background="LightGreen" > 
<Button HorizontalAlignment="Left" IsEnabled="True" Margin="13.5,5,0,5" Name="TestBtn" Width="50" Click="test_Click" >Test</Button> 
</Grid> 

<Grid Name="Grid3" Grid.Row="2" DockPanel.dock="Top" Background="LightGray" Height="auto" > 

</Grid> 
</DockPanel> 




private void test_Click(object sender, RoutedEventArgs e) 
    { 
    tGrid1.visibility=visibility.collapsed; 
Grid2.visibility=Visibility.collapsed; 
    } 

这工作正常。 谢谢 Kaja

不知道这是你在问什么，但在test_Click方法，你可以这样做：用“崩溃”你的意思是“隐藏”

private void test_Click(object sender, RoutedEventArgs e) 
    { 
    tGrid1.Width = 0; 
    tGrid1.Height = 0; 
    Grid2.Width = 0; 
    Grid2.Height = 0; 

    Grid3.Height = 465; 
    Grid4.Height = 35; 
    } 

如果这将通过设置tGrid1和Grid2的height和width工作，以0
